“…To the best of our knowledge, this is the first report on F. commune causing crown and root rot on T. grandis globally. Fusarium oxysporum has been reported to infect T. grandis and induced crown and root rot in China, but the symptoms were characterized by brownish black necrotic areas on the roots and often advanced to the collar on most plants (Zhang et al., 2016). In our study, the crown was infected first and the roots were infected only in the later stages of the disease.…”

Torreya grandis cv. Merrillii is an important economic tree widely cultivated in hilly subtropical areas in China and some parts of Japan and Korea. Crown and root rot was found on T. grandis in Zhejiang Province of China. Three isolates with similar morphology were isolated from diseased samples, and used for identification and pathogenicity tests. The pathogenicity of the isolates was confirmed by fulfilling Koch's postulates. The pathogen was identified as Fusarium commune based on morphological characteristics and phylogenetic tree constructed by combining ITS and TEF‐1α gene sequences. This is the first report of F. commune causing crown and root rot on T. grandis in China.
